PI72854: MQ V9: CSQE112E I/O ERROR WHEN ARCHIVE LOG DATASET SPANS MULTIPLE VOLUMES

Obtain the fix for this APAR.

APAR status

• Closed as program error.

Error description

• MQ v9:
  MQ does not correcly identify when an archive log dataset spans
  multiple volumes.  MQ treats the dataset as if all log data is
  accessible on the first volume.  If recovery processing needs to
  read data from a later volume, a POINT request is issued for a
  location which is beyond the end of the volume, and the
  subsequent read results in an I/O error.
  
  If the I/O error occurs while
  recovering a structure, it is reported by message CSQE112E.

  ****************************************************************
  Read routines for DASD archive logs fail to locate the correct
  volume in a multi-volume dataset for a specific RBA range
  generating abend 5C6-00D10329.
  

Problem conclusion

• Archive log read routines have been corrected to locate all the
  volumes in a multi-volume dataset.
